Abstract
The paper develops a new cellular-assisted radio surveillance and tracking technique with an Unmanned Aerial Vehicle (UAV) being the mobile receiver and a static cellular ground base station (BS) being the illuminating source. Under the proposed framework, the resolution of the radio surveillance and imaging depends critically on the relative positions (or geometry) between the UAV, BS and target, as well as the instantaneous motions of the UAV and target. A novel UAV navigation law is developed to guarantee that after some time, the range resolution, the azimuth resolution and the distance between the UAV and the moving target will be below some given upper limits. Its mathematically rigorous analysis is presented. Simulations demonstrated the effectiveness of the developed navigation law.
